Abstract
Aiming at the wing icing problem,the icing degree parameter was used to describe the ice effects on aircraft aerodynamic parameter;This parameters was introduced into nonlinear six degrees-of-freedom dynamic model of plane;A time-varying simulation model was established with Simulink,which varying with this parameter;By comparing the simulation result with flight test data,the correctness of this is verified;A pitch angle keeping model of closed loop simulation system is designed;In certain flighticing conditions,the open-loop and closed-loop flight simulation were performed;Through the open loop system simulation,studied the effect of ice accretion on aircraft trim characteristics,the flying state and the pilot response effect were also simulated;Through the closed-loop system simulation,the flight status affected by ice accretion processes and the corresponding response of aircraft control was simulated.The simulation results showed that the ice accretion has adverse effects on trim characteristics,aircraft response and automatic driving performance.It's a threat to flight safety.关键词
